Question

我正在研究struts2 Hibernate，在我的项目中我将一个文本文件（普通/文本）上传到数据库，所以现在我需要从数据库中动态下载该文件，我尝试搜索所有网站，我没有得到适当的输出。我无法继续我的项目，请帮助我。

此代码适用于struts2 Action类的上传文件：

Recruitment rc = new Recruitment();  

public String saveOrUpdate() {
    //  String returnString = ERROR;

     HttpServletRequest request = (HttpServletRequest) ActionContext.getContext().get(ServletActionContext.HTTP_REQUEST); 
       HttpSession session1 = request.getSession(true);        


    rc.setImgcontenttype(getUserImageContentType());
    rc.setPhotoname(getUserImageFileName());

    rc.setCandidatename1(getCandidatename());
    rc.setQualificationid1(getQualificationid());
    rc.setSkillid1(getSkillid());
    rc.setExperience1(getExperience());
    rc.setResumedate1(getResumedate());
    rc.setInterviewdate1(getInterviewdate());
    rc.setReference1(getReference());
    rc.setResultt1(getResultt());
    try {
        rc.setPhotodata(FileUtils.readFileToByteArray(getUserImage()));
    } catch (IOException iEx) {
        iEx.printStackTrace();
    }
    setRphotobo(rc);
    System.out.println("JJJJJJJJJJJJJJJJJJJJ " +rc.getCandidatename1());     
    System.out.println("imageklkkkkkkkkkkkkkkkkkkkkkkk" + rc.getImgcontenttype());
    System.out.println("HHHHHHHHHHHHHHHHHHHHHHH " + rc.getPhotoname());
    System.out.println("GGGGGGGGGGGGGGGGG " + rc.getPhotodata().toString());         
      System.out.println("Jkkk" +getUserImageFileName());      
    recruitmentDAO.saveOrUpdateRecruitment(rc);






    return SUCCESS;

}

我正在寻找下载代码。
